This standard is equivalent to The standard IS-343:1983 conveyor flat top chains and sprockets has the following requirements: In the TS4.1%:19H conveyor flat top chains and sprockets notes, the sizes, tables and calculation formulas of chains and sprockets are divided into English and metric. The standard only adopts metric sizes and formulas for single and double cuts, and the notes have made some editorial changes to the text: the calculation formula for the cross-sectional measurement M has been corrected. This standard replaces GT40-150 conveyor flat top chain and sprocket. This standard is different from 6K41401993 cabinet. The change of the station has cancelled the heat setting of the chain stealing direction:
ground specification. The calculation of the public support and the note of the profit have been cancelled. The "radius" of the A\ solid plate has been cancelled.

the actual sprocket technique is the most economical and comprehensive method, and it is designed to be unique, and it can better absorb the load and form a suitable seal. This design is a light change, and the wheel manufacturer will consult: the sprocket can be single or single tooth, and the single cut wheel has a group of effective teeth in the middle position of the single tooth sprocket. Under this condition, the effective tooth effect of the sprocket must be an integer. The mathematical specification of the effective tooth of the sprocket is based on the actual tooth effect 14140-2003/1S04348:1383

Figure 6 Measuring distance of the sprocket
For the sprocket with a certain number of teeth, the measuring method is to measure the two measuring columns that match the sprocket in the two teeth corresponding to the sprocket in the direction of the sprocket.
For the sprocket with a special concave shape, the measuring method is to measure the two measuring columns that match the key wheel and the base in the two teeth corresponding to the upper rod as close as possible to the wheel diameter.
During the measurement, the total amount of data is enough to contact the two tooth roots of the chain wheel. 3.2.2.5 Tooth circle diameter
